We know that Normally, the number of voltage intervals is given by

a). Resolution

• $N=2^M \cdots\mathrm{Equation \ 1}$.......(1)

where M is the ADC's resolution in bits

• Thus from equation 1 , we obtain

$Resolution \space (N)=2^8=\bf256 \space \text{quantization levels}$

• ADC voltage resolution is given by,

$Q = \dfrac{V_i }{ (2^M-1)} …
